ABSTRACT:
A snow ski is provided including generally flat toe and heel sections and an arched center section extending between and interconnecting the toe and heel sections. The opposite side marginal edges of the bottom of the ski define snow biting edges for biting into an underlying snow surface when the ski is angularly displaced about its longitudinal axis relative to the snow surface and an intermediate length portion, only, of the snow biting edges extending along the heel section are modified to effectively reduce the capability thereof to bite into an underlying snow surface while the snow biting edges of the toe section of the ski are modified to increase the capability thereof to bit into the underlying snow surface. Further, the ski includes a prdetermined toe binding area mounting location thereon spaced appreciably forward of the longitudinal mid-point of the ski, these features enabling elementary and intermediate level skiers to more readily "pin" the toe section of the ski when executing turns and allowing the heel section to controllably drift outward during the execution of a turn.
